    • A Chemical and kinematical analysis of the intermediate-age open cluster IC 166 from APOGEE and Gaia DR2 
      Schiappacasse Ulloa, J.; Tang, B.; Fernández Trincado, J. G.; Zamora, O.; Geisler, D.; Frinchaboy, P.; Schultheis, M.; Dell'Agli, F.; Villanova, S.; Masseron, T.; Meszaros, Sz.; Souto, D.; Hasselquist, S.; Cunha, K.; Smith, V. V.; García Hernández, D. A.; Vieira, K.; Robin, A. C.; Minniti, D.; Zasowski, G.; Moreno, E.; Pérez Villegas, A.; Lane, R. R.; Ivans, I. I.; Pan, K.; Nitschelm, C.; Santana, F.; Carrera, R.; Román Lopes, A. (IOP Publishing, 2018-09)
      IC 166 is an intermediate-age open cluster (OC) (similar to 1 Gyr) that lies in the transition zone of the metallicity gradient in the outer disk. Its location, combined with our very limited knowledge of its salient ...
    • Cool stars in the Galactic center as seen by APOGEE: M giants, AGB stars, and supergiant stars and candidates 
      Schultheis, M.; Rojas Arriagada, A.; Cunha, K.; Zoccali, M.; Chiappini, C.; Zasowski, G.; Queiroz, A. B. A.; Minniti, D.; Fritz, T.; García Hernández, D. A.; Nitschelm, C.; Zamora, O.; Hasselquist, S.; Fernández-Trincado, J. G.; Muñoz, R. R. (EDP Sciences, 2020)
      The Galactic center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and stellar crowding. Large, near-IR spectroscopic surveys, such as ...
    • GJ 832c: a super-earth in the habitable zone 
      Wittenmyer, Robert A.; Tuomi, Mikko; Butler, R. P.; Jones, H. R.; Anglada Escudé, Guillem; Horner, Jonathan; Tinney, C. G.; Marshall, J. P.; Carter, B. D.; Bailey, J.; Salter, G.

      We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an Mdwarf previously known to host a Jupiter analog in a nearly circular 9.4 yr orbit. The combination of ...
    • Proper motions in the VVV Survey: Results for more than 15 million stars across NGC 6544 
      Contreras Ramos, R.; Zoccali, M.; Rojas, F.; Rojas Arriagada, A.; Gárate, M.; Huijse, P.; Gran, F.; Soto, M.; Valcarce, A. A. R.; Estévez Valencia, Pablo; Minniti, D. (EDP Sciences, 2017)
      Context.In the last six years, the VISTA Variable in the Vía Láctea (VVV) survey mapped 562 sq. deg. across the bulge and southerndisk of the Galaxy. However, a detailed study of these regions, which includes∼36 globular ...
    • Searching for faint comoving companions to the alpha Centauri system in the VVV survey infrared images 
      Beamín, J. C.; Minniti, D.; Pullen, J. B.; Ivanov, V. D.; Bendek, E.; Bayo, A.; Gromadzki, M.; Kurtev, R.; Lucas, P. W.; Butler, R. P. (Oxford university press, 2017)
      The VVV survey has observed the southern disc of the Milky Way in the near-infrared, covering 240 deg(2) in the ZYJHKs filters. We search the VVV survey images in a similar to 19 deg(2) field around alpha Centauri, the ...

      Minniti, D.; Saito, R. K.; Forster, Francisco; Pignata Libralato, Giuliano; Ivanov, V. D.; Lucas, P. W.; Beamin, J. C.; Borissova, J.; Catelan, M.; González, O. A.; Hempel, M.; Hsiao, E.

      We report the discovery of an enigmatic large-amplitude (DKs > 10.5 mag) transient event in near-IR data obtained by the VISTA Variables in the Via Lactea (VVV) ESO Public Survey. The object (designated VVV-WIT- 06) is ...
